【摘要】:为揭示添加平菇或香菇菌糠对木耳菌糠-鸡粪堆肥的效果,通过腐殖质组成特征筛选适宜的配方,将风干、粉碎后的平菇或香菇菌糠添加到木耳菌糠-鸡粪堆料中[平菇菌糠∶木耳菌糠∶鸡粪分别为3∶4∶3(Ⅰ-1)、2∶4∶4(Ⅰ-2)、1∶4∶5(Ⅰ-3),香菇菌糠∶木耳菌糠∶鸡粪分别为3∶4∶3(Ⅱ-1)、2∶4∶4(Ⅱ-1)、1∶4∶5(Ⅱ-1)],进行为期90 d的好氧堆腐试验,探索不同配方对堆料总有机碳(TOC)、胡敏酸碳(C_(HA))、胡敏素碳(C_(Hu))含量,胡富比(C_(HA)含量/C_(Hu)含量),胡敏酸(HA)碱溶液在465、665 nm处光密度比值(E_4/E_6)的影响,进而确定平菇或香菇菌糠与木耳菌糠-鸡粪间的最优配比。结果表明:与10 d相比,堆腐90 d后,除了Ⅰ-1处理能使堆料TOC含量得以累积,使其增加4.0%外,其余处理均可促进TOC的矿化;Ⅰ-1处理对堆料C_(HA)的消耗程度最大,而在2∶4∶4和1∶4∶5两个配比下,添加香菇菌糠(Ⅱ-2、Ⅱ-3)比平菇菌糠(Ⅰ-2、Ⅰ-3)更有利于木耳菌糠-鸡粪堆料C_(HA)的矿化分解;除了Ⅱ-3处理能使HA碱溶液E_4/E_6有3.9%的增加外,其余处理均可促使E_4/E_6下降,使HA的缩合度和芳构化程度提升,Ⅱ-1处理的优势最为明显,其次是Ⅰ-2处理;在堆料腐解期间,胡富比均有所降低,其中Ⅰ-1处理的降低幅度最大,Ⅰ-2和Ⅱ-3处理可促进菌糠堆肥的腐熟;在分解胡敏素(Hu)方面,Ⅰ-2处理更有优势,其次是Ⅱ-2和Ⅱ-3,而Ⅰ-1、Ⅰ-3和Ⅱ-1处理对Hu组分的降解能力相对较弱。平菇菌糠、木耳菌糠、鸡粪间质量比为2∶4∶4(Ⅰ-2)时更有利于堆料HA缩合以及Hu降解,最终促使堆料腐熟。
